Beit lmown that I, Jon DANeUIovIoH, a sub3ect of the Emperor ofAustria-Hun? gary; residingfat Ely, in the county of St.

vvirs Aknov'vn, ,therporton ot the spike which en-A gages the undersurface of the head of the rail; is-.intesralwth the spike proper, andwhen itis-desired to-bring. this upper part of the Spike into engagementwith the rail, it iS 'neeeeeary 1tobend the same after the spike S has,been driven into place. .This bending .ofthe head engaging partbyhammeringeauses the. shankfo the spiketo be loosened, thereby. renderingtho clamping of the frailinsecure. It is to obvate this de'- .fao

feet and to provideanefficient holding means orrailroad rails that thepresentim' ventio'n has 'been devised. f'j, '1`he object of myinvention, therefore, is improve the construction of railroad '.fspikesof the general type-Bibv .referred to,

whereby their durability, strength and 'utility .are increased and toprovide a simple vand' in'expensive ldevice particularly adapted foremployment' on curves and capable of el'ectuall-y preventing rails fromspreading. The invention consists in the construction and novelcombination and arrangement of partsfheieinafter described, illustratedin the accompanying drawings'and more ai'- ticularly pointed out'in theappended claims. In the drawings.Figure 1 is a; vertical section ofa-rail and tie showing my in vention 'used in l'connection therewith.Fig. 2- is` a top plan view showing the head of the railv removed. forthe pu ose of clearness.

tool.

from movin part is placed on the pin 11 wi A My improved devicecomprises a main portion 1? and a movable locking portion 10. The main'portion 1 consists of a base plate 3 having on its underside, near'itsinner edge, a rabbet 4 for en aging the upper surface-of vthe rail base.ntegral with the underside of the base plat-e3 and preferably disposedin the center thereof, isa trangular shaped-shank 5 and on the outeredge of saidbase'plate are downwardly depending short Shanks .6. TheseShanks form additional securing means for the spike and which will`prevent the latter from/loosening.

.A vertically extending pin 7 having a horizontally disposed opening 8is provided yupon the upper surface of the base'plate 3 and horizontallugs 9 are placed on lthe sides of said base plate to facilitate thewithdrawal of the spike by a claw or other The movable locking portion10 consists of a block having a vertically vdisposed I '80 vaperture 11which engages the pin 7 when the two parts of the spike are united. Aout away portion or rabbet 12 is provided in said block and the uppersurface of vthe ,block is substantially horizontal, as shown at 13, tofit under Jthe head ofthe rail. A curved surface 14 extends upwardlyfrom the bottom of the block to the horizontally disposed suracel, on'the sideopposite to the rabbet 12 to engage the web of the rail.

The block is preferably provided with an opening .15, which communicateswith the horizontal opening 11, for the assage of a. bolt 16. When thelocking member is turned on the pin 7 to locking position the bolt '16is passed through the opening 15, and the opening 8 in the pin 7, tosecure said block on said base. A Cotter pin 17 is passed through saidbolt -to retain the same in place.

Patented aug. 18, 1914.

An ear 18, havin an opening 19 for the insertion of a suita le tool, isprovidedon the side of said block by means" of which the block may beturned. on its pivot. f

Inthe operation of my device, the Shanks of the part 18L are firstdriven into the tie and the rabbet 4 brought into contact with' theupper surface of the base of the rail, the

contact with the rail being maintained by the short Shanks 6, whichprevent the 4spike laterally and the consequent spreading o the rails..When the shank .of the 'part l" has been driven into tpllace, the

its rabbet'lQ toward the rail head. -A tool is then inserted in theaperture 19 and the part 10 turned on its pivot to bring the surface 13into Contact with the underside of the head of the rail and the upperportion of its curved surface la into engagementv with the rail web. Thepin 16 is then inserted through the openings 15 and 8 which securelylocks the two parts of the spike in operative position.

The device has the following meritorious features: The spike Which issimple and comparatively inexpensive in construction, is adaptedparticularly for use on curves and switches, Where the rails aresubjected to amaximum longitudinal and lateral presi sure, and it willetfectually prevent the rails from spreading and getting 'out of,alinement.

It will be appreciated b those skilled in the art, that the device sovvn is merely typical and may be modiied or kvaried in many waysWithout departing from the spirit or sacrificing any of the advantagesof this invention as set forth in the claims annexed.

lVhat I claim and desire to secure by Letters Patent is 1. A spikecomprising a base having nzeans for securing the same to a railway tie,and a locking member pivotally mounted on the top of said base, andadapted to member pivotally mounted on the top of said base, and adaptedto engage the under surface of the head of the-rail.

.4. A spike comprising base having a shank for engaging the tie, a pinprovided upon the upper surface of said basei and a locking blockmounted upon. said pin, said block having a high side and a lovv side,the locking block being adapted to be piace'd on said pin with its lowside to iard the. ".aw and then turned to bringthe high side inengagement With the head and web of L' f if rail.

5. A spike comprising bas-e hav shank for engaging the tie, a locking bi pivotally mounted on said base, and' roec tions provided on the sideof said, base. whereby the Withdrawal of said spike may be facilitated.-

6..A spike comprising a base having shank for engaging the tie, a pinprovided upon said base, a locking block loosely mounted on said pin,and means for locking said block'upon said pin.

7. A spike comprising a base having a shank for engaging the tie, a pinprovided upon said base and a locking block loosely mounted on said pinand having a cut away portlon on one side thereof, a curved surface onthe opposite side and a horizontal surface connecting said curvedsurface and said cut away portion, said block being adapted to be placedon said pin with its cutaway side toward the rail and then turned tobring 'the horizontal surface into Contact with thermderside vof thehead 'of the rail andthe up per portion of the curved surface-into engagement with the rail Web.

In testimonyl whereof I aiiiX my signature, 'in the presence of twoWitnesses.
